This patch allows the usage of the `track_caller` annotation on
generators, as well as sets them conditionally if the parent also has
`track_caller` set.
Also add this annotation on the `GenFuture`'s `poll()` function.
The fluent argument syntax is a little special and easy to get wrong, so
we emit a small help message when someone gets it wrong.
Example:
```
parser_mismatched_closing_delimiter = mismatched closing delimiter: `${delimiter}`
```
panics with
```
thread 'rustc' panicked at 'Encountered errors while formatting message for `parser_mismatched_closing_delimiter`
help: Argument `delimiter` exists but was not referenced correctly. Try using `{$delimiter}` instead
attr: `None`
args: `FluentArgs([("delimiter", String("}"))])`
errors: `[ResolverError(Reference(Message { id: "delimiter", attribute: None }))]`', compiler/rustc_errors/src/translation.rs:123:21
```
Fix `rustdoc --version` when used with download-rustc
Previously, rustdoc would unconditionally report the version that *rustc* was compiled with. That showed things like `nightly-2022-10-30`, which wasn't right, since this was a `dev` build compiled from source.
Fix it by changing `rustc_driver::version` to a macro expanded at invocation time.

Cleanups in autoderef impl
Just something I noticed. Turns out the `overloaded_span` is not actually used separately from the main span, so I merged them.
Cleanup Apple-related code in rustc_target
While working on https://github.com/rust-lang/rust/pull/103455, the consistency of the `rustc_target` code for Apple's platforms was "kind of bad." There were two "base" files (`apple_base.rs` and `apple_sdk_base.rs`) that the targets each pulled some parts out of, each and all of them were written slightly differently, and sometimes missed comments other implementations had.
So to hopefully make future maintenance, like implementing https://github.com/rust-lang/compiler-team/issues/556, easier, this makes all of them use similar patterns and the same target base logic everywhere instead of picking bits from both. This also has some other smaller upsides like less stringly-typed functions.
Add support for custom mir
This implements rust-lang/compiler-team#564 . Details about the design, motivation, etc. can be found in there.

Add context to compiler error message
Changed `creates a temporary which is freed while still in use` to `creates a temporary value which is freed while still in use`.
Migrate rustc_codegen_llvm to SessionDiagnostics
WIP: Port current implementation of diagnostics to the new SessionDiagnostics.
Part of #100717
```@rustbot``` label +A-translation
Previously, a `delay_span_bug` was isssued, failing normalization. This
create a `TyKind::Error` in the signature, which caused
`compare_predicate_entailment` to swallow its signature mismatch error,
causing ICEs because no error was emitted.
